I know that different tires and trannys will play a role, but I was wondering what the ideal gears are on mid to high 9 sec buicks, do they stick with the 3:42's or is it just personal preference?
i think 342 gears with 28 in tall tires should get you there also depends on your tranny i think the guyswith 400 trannya might be using 3.90 and 411 gears
